Vitamin C, E supplementation raises pregnancy risks

A study showed women who took prenatal vitamins C and E did not have lower rates of pre-eclampsia or gestational hypertension but did have a higher risk of fetal loss or perinatal death and preterm prelabor rupture of membranes. Researchers said they can't recommend the supplements for pregnant women at the doses studied, 1,000 milligrams of vitamin C and 400 IU of vitamin E, because of concerns over adverse pregnancy outcomes.
